Description

Technical Field

[0002] The damping hinge is a hydraulic buffer hinge that uses the buffering properties of liquid and has an ideal buffering effect. The door starts to close slowly at 60°, reducing the impact force and forming a comfortable damping hinge effect when closing. Large hinge dampers involve many parts and will be pre-installed before assembly, that is, large and small O-rings are installed inside and outside the Rotor rotor respectively. The damper will be filled with oil during use, and the large and small O-rings play a sealing role. To ensure the sealing effect, the outer diameter of the small O-ring is slightly larger than the rotor aperture, and the inner diameter of the large O-ring is slightly smaller than the outer diameter of the rotor, which is difficult to install.
